CHARLES J. IiUCiE, OF NIANTIC, CONNECTICUT, ASSIGNOR, BY MESNEASSIGNMENTS,

TO STANDARD COMPRESS AND WAREHOUSE VIRGINIA.

Application filed June 20, 1913, Serial No. 774,802.

To all whom it may concern:

Be it known tliatl, CHARLES J. Loon, a citizen of the United States,residing at Niantic, in the county of New London and State ofConnecticut, have invented certain new and useful Improvements inCotton- Compresses, of which the following is a specification.

This invention relates broadly to cotton compressors, and moreparticularly is designed to provide compressing apparatus adapted for asecondary or other subsequent. and more compact and accurate compressionof a preliminarily and usually roughly and approximately pressed bale.The particular structure in which the invention is embodied includes aset of end compressor members whereby the bale is endwisely compressed,a set of side compressor members whereby the bale is next sidewiselycompressed, and upper and lower compressor members or platens betweenwhich the bale is given a vertical compression.

One of the objects of this invention is to provide an apparatus of theabove character, preferably controlled and actuated by hydraulic orother fluid means adapted for simple and accurate operation. 7

Another object of the invention is to provide in this connection a typeof hydraulic or equivalent means so arranged and constructed thatautomatic actuation of the plurality of compressor members controlledthereby may predeterminedly take place in proper sequence.

A further object of the invention is to provide a set of members forendwisely compressing a bale, and a set of members for sidewiselycompressing the bale, together with a common means for actuating suchsets of compressor members in desired sequence.

Still another object is to provide lever or equivalent connections forcertain of the last named compressor members, under control of thehydraulic actuating means, whereby the effective leverage upon suchcompressor members increases in accordance with the advance ofcompression; whereby when the compression induced by said compressormembers is at its desired maximum the compressor members will be held inlocked condition, without requiring any additional or speciallockingmeans; and whereby, in con- Specification of Letters Patent.

the compression of certain of the compressor members may be graduallyeased down and released, without shock and without tendency todistortion of the bale.

Another object of the invention is to provide, in connection with thehydraulic or equivalent compressor-member operating means, attachmentsand arrangements whereby the comparatively slight endwise and sidewisecompression and the initial vertical compression takes place rapidly,whereby the succeeding vertical or final compression takes place moreslowly, but with proportionate increase of power.

Other objects and aims of the invention,

more or less broad than those stated above, together with the advantagesinherent, will be in part obvious and in part specifically referred toin the course of the following de scription of the elements,combinations, arrangements of parts, and applications of principlesconstituting the invention; and the scope of protection contemplatedwill appear from the claims.

Each of these side doorscarries thereon a= presser-plate' 49 supported by the I-beains 43 asshown in Fig. 2. Each hinge rod 27 is supported at its lower end bymeans of a rigidly .connected tracker member 51 which rides upon a track52 (Fig. 1) and the upper end of the rod ,moves within a slot 53 formedin one of the slotplates 54 carried as shown in Figs. 1, 2 and 3, uponroof-member 28, a correspondingly slotted casting 54 overlying theplates 54 above the slot 53 to protect the end of the rod. With thesidedoors22preparatorily swung inwardly to take up the location shown at 22in Fig. 2 as aforesaid, the

hinge rods 27 rest in said slots 53 (and correspondingly 011 said tracks52) as disclosed in Fig. 2, that is, parallelly spacedaway to themaximum fromthe longitudinal centerline 55-55 shown in Fig. 2.

as most clearly shown in the detail disclosures of Figs. 17 and 18, andare adapted when horizontally overlapping each other to a lesser extent,as in said Figs. 17 and 18, to.

maintain the hinge rods 27 of doors 22 parallelly spaced away to themaximum from thedOngitudinal center-line 55 55 shown in Fig. 2; and, asmost clearly shown in Figs. 13 and 14, are adapted when horizontallyoverlapping each other toa greater extent,to draw the hinge rods 27" ofside door's '22 inwardly toward said center-line 5555; that is, to therods 27 to the" other'extremity'o't each slot 53 from the ex'- treinityillustrated in Fig. 2, and simuItane ously to cause the tracker member51 to travelaway fromthe observer upon the track shown in Fig; 1; Therelative slidov ment of bars 44 and aag to kinda ne'i; the hmgereds'ev'teward each" ether-er is move them away from each other is broughtabout by means of links 56 and 57, the link 56 in each case beingconnected to the bar 45 by means of a pivotal connection 58 to adepending U-lug 59 atthe inner end of bar 45, and the link 57 in eachcase being connected by a similar pivotal connection 60 to a U-lug 61 atthe inner end of bar 44. The bar 44 slides between the legs of the U-lug 59 above the pivot 58 and thebar 45 slides above the pivot60 andbetween the pivot 60 and a'pin 62 that extends between upwardlyextending side pieces 63 that are continuous with the legs of the U-lug61. There are two sets of these links 56 and 57, connected to thesliding members 44 and 45 reciprocating bars 64 find a way in the spacebetween the two pairs of fingers 46"(see Figs. 8, 9 and 10). lhe extremepositions of this reciprocating bar 64 are shown in Figs. 14 and 18respectively, Fig. 14 showing the bar 64 in its uppermost position, withthe sliding members 44 and 45 overlapping each other so as'to draw thehinge rods 27 showing the lowermost position of" the reciprocating bars64, with the slidingmembers 44 and 45 moved to the position in which thehinge rods 27 are moved away from each other. The operating means forthe hinge rods are thus in efiect a series of identically andsimultaneously acting toggles, and when the links 56 and 57 haveposition except upon the positive toward each other, and Fig. 18

application of power to move the reciproeating bars 64 downwardly.Furthermore,

by the employment of these cross-over toggles, the leverage increases asthe hinge rods are brought closer together, this increase correspondingwith the advancing sidewise compression and consequent increasingresistance.

The locking rods 41 carriedby the various links 38,'wh-ich as abovesuggested are provided to engage with the keepers or retainers 42carried by the side doors-22 when the side doors are brought to theposition in'dicat'ed' "area-1a Figs, are intended 'to be 'draWn'ISOtogether and forced apart in the same manner' as and concurrently withthe relative movements of the hinge rods 27. To that end the links 38are pivotally connected to sliding pieces 39 and 620, as shown in Figs.11, 12, 15 and 16, which sliding pieces 39 and to correspond to thesliding members M and 15, and are connected by means of links 65 and 66,corresponding to the links 56 and 57 previously described, toreciprocating bars 67 corresponding to the reciprocating bars 6stpreviously described in connection with the actuation of the hinge rods27 The locking rods 11 are thus actuated in substantially the samemanner as and simultaneously with the hinge rods 27, sothat, assumingthe parts to be in the position shown at 22 in Fig. 2, if the bars 6%and 67 are simultaneously moved from the position which theyrespectively occupy in Figs. 18 and 16 to the positions which theyrespectively occupy in Figs. 1+1 and12, the side doors or compressormembers 22 will be brought from the position indicated at 22 to theposition indicated at 22" in Fig. 2, and upon a reverse movement of thereciprocating bars 64.- and 67, the side doors 22 will be brought fromthe position indicated at 22 to the position indicated at 22. The

drawing of the side doors together will of course compress a balesidewise, and the separation of the side members 22 will release thesidewise compression.

For the endwise compression of the bale, and cotiperative with thesidewise compressors 22, I provide end doors 68, each of which iscarried by a support 69 that is pivoted to the frame-work as indicatedat 70. The open position of these end doors 68 is shown in Fig. 4, andthe closed position thereof is shown in Fig. 1, for instance.

Each ofthese end doors 68 carries on its outer face a pair ofprojections 71 having an inclined face 72 and a face 7 1 that isparallel to the face of the door 68. Cotiperating with the surfaces 72and 74 of the pro jections 71 are rollers 75 mounted on a shaft 76, andthis shaft 76 also carries a pair of rollers 77 that coiiperate with thesurfaces of projections 78 upon castings 79 that are secured uponsupporting rods 27. It will be evident that if the shaft 76 is movedfrom the position shown in Fig. 10, for instance, to the position shownin Fig. 7, the door will be brought to a vertical position. Thismovement of the shafts 76 is brought about by means of the hydraulicrams 31, the heads 80 of which are connected to the shaft 76 by means ofparallel links 81, so that as the head of the ram rises from theposition shown in Fig. 10, for instance, to the position shown in Fig.7, the rollers 75 and 77 will be forced between the opposing surfaces ofthe projections 71 on the end doors and the opposed projections 78 onthe castings 79. While the rollers 7 5 are traversing the inclinedsurface 72 of the projections 71 the door is gradually straightened upto a vertical position, and when the rollers 75 reach the surfaces 74their further upward vertical travel causes no further movement of thedoors 68. The rams 31, besides causing the actuation of the end doors68, are intended also to actuate the several pairs of reciprocating bars64: and 67, so as to operate the side compression members. This isaccomplished by providing the head of each ram 31 with an upstandingpart 82 carry ing a pin 84 that projects on opposite sides and extendsthrough elongated slots 85 in the lower ends of the two reciprocatingbars 64: or 67 as the case may be. Assuming the parts to be in theposition shown in Fig. 8, if the head of the ram begins to rise, thefirst effect will be to carry upwardly the links 81, whereby the doors68 are brought to the vertical position. At the moment when the rollers7 5 reach the surfaces 74 of the projections 71, the pins 84 havereached the lower ends respectively of the slots 85 in the pairs ofreciprocating bars 64: and 67, and the lower ends of said reciprocatingmembers 64 and 67 are in contact with the head of the ram adjacent thebase of the up: standing part 82, so that as the head of the ramcontinues in its upward course, it carries the pairs of reciprocatingbars 64 or 67 with it, thereby straightening out the toggles and drawingthe side doors or compressor members toward each other in the manneralready described. Thus it will be evident that the end doors arebrought. to the vertical position first, and before the side doors beginto approach each other. As these side doors approach each other, lockinggrooves 86 which are formed therein engage the edges of the end doors68, thereby forming a complete box, the parts of which are securely heldtogether. Preferably the mouths of these grooves 86 are beveled-off asshown, so as to guide the end doors into place and also to prevent shockwhen the compression is released and the side doors begin to separatefrom each other. if it were not for this provision, when the side doorsseparate the end doors would suddenly snap out of the grooves 86 onaccount of the endwise expansion of the bale, and there iVOlllClbB atendency to distortion of the ale.

Assuming that the end doors have been straightened up in the mannerdescribed, and that the side doors have thereupon been drawn togetherandinterlocked with the end doors, so that the bale has been subjectedto endwise and sidewise compression,

the next step is to cause verticalcompression 2 to re i a hern in isewas r 1% upwardly at a comparatively rapid rate of speed, and that whenthe compression has advanced to a certain predetermined stage at whichthe resistance of the bale becomes greater, the pressure shall beadmittedalso to the middle and larger cylinder, after which theelevation of the platen continues more slowly but with increased power.How all this is accomplished will be best understood from thedescription of the hydraulic apparatus and controls hereinafter andsidewisely and vertically compressedin the manner stated, thecompression of the side doors is first released; then the end doors moveback to the position shown in Fig. 4, whereupon the side doors may bereleased from their locking rods 41 and swung open to the position shownin full lines in Fig. 2. Meantime, the movable platen 26 is held in itselevated position shown in Fig. 4, and the securing bands 87 are passedaround the bale by way of the alined. dovetail grooves in the fixed andmovable platens. These grooves are larger at the bottom so that thebands may be readily inserted, and are contracted at their months sothat as the bands are drawn taut they are properly guided and alined.The coverfor the bale will of course have been put in position beforethe compression is initiated, and since thebale is slightlyovercompressed vertically, the ends ofthe cover I at 88 the usual tankfor the hydraulic system, and at'89 there is indicated a pump.

From the pump leads a pipe 90, with an interposed pressure valve 91,which pipe 90 connects by means of the pipe 92 with the two endcylinders 24. From the pipe 90 there is also a branch 94 which connectswith a pipe 95 leading to the middle and larger cylinder 24', the branchpipe 94 being provided with a pressure valve 96. The pressure valves 91and 96 are of such construction respectively that the pressure valve 91will open upon a less pressure than the pressure valve 96, so that thefluid will be sent to the end cylinder 24 first, and will not be sentinto the middle or larger cylinder 24' until pressure has increased to apredeterdescribed. When the bale has been endwisely mined point. Thepipe 95-is connected by a I pipe 97 and a pipe 98 with the tank 88, andthere is a check valve 99 in the pipe 97, so that as the two end rams 25begin to rise, carrying with them of course the middle or larger ram 25,the suction induced by the latter in the pipe 95 will cause the fluid topass from the tank 88 through the pipes 98 and 97 past the check valve99 into the pipe 95 and following the rising ram in the larger middlecylinder 24. Thereupon, as the pressure rises, the pressure valve 96opens and the pressure enters the pipe 95, so that the active fluidpressure will then be operating within all three of the cylinders 24'.The provision of the check valve 99 and the con nection to the tank 88insures that there will be inert fluid behind the larger central ram 25at the moment when the active pressure is turned into the middlecylinder, so that no time is lost in pumping the fluid into this middlecylinder. The pipe 95 is also connected to the tank 88 by another pipe100, in which pipe 100 there is a globe valve 101, the purpose of whichis to empty the middle cylinder 24 when the pressure is released. Alsocommunicating with the pipe 90 there is a pipe 102, which connects witha pipe 104 that opens into a union controlled by a three-way valve 105.This valve 105 controls the passage between pipe 104 and a pipe 106 thatleads directly to the lower end of one of the cylinders 81, and by meansof a branch 107 to the lower end of the other cylinder 81. The valve 105also controls the passage between the pipe 104 and a pipe 108 that leadsinto the tank 88 by way of the pipe 98.- 109 indicates a unionconnecting the pipe 102 with the pipe 104 and with another pipe 110, andin the pipe 104, between the union 109 and the three-way valve 105 thereis a check valve 111, which opens toward the three-way valve 105. Thepipe 110 is connected by means of a threeway valve 112 with a pipe 114and with another pipe 115. The pipe. 114 leads directly to the top orthe cvlinder 81, and by means of a branch 116 to the top of the othercylinder 81; and the pipe 115 leads to the tank 88. In operation thethree-way valve 105 is turned so that the fluid from the pump passesthrough the pipe 90, pipe 102, through check valve 111, through pipe 106to the bottom of one cylinder 81, and through the branch 107 to thebottom of the other cylinder 81, The passage from pipe 104 to pipe 108is closed in this position of the three-way valve 105, and at the sametime the three-way valve 112 is turned so that there can be nocommunication between the pipe 102by way of the union 109 and the pipe110 with the pipes 114 or 115. Upon the admission of pressure in thisway to the lower ends of the cylinders 81, the rams in the cylindersbegin to rise, thereby first straightening up the end doors 68, andafterward drawing together the hinge rods 27 and the locking rods ll ofthe side compressor members. This being accomplished, as the pumpingcontinues and the pressure increases, the pressure valve 91 opens andfluid is admitted through this pressure valve 91 into the piping 92,whereupon the two end rams of the three rams that control the movableplaten 26 begin to rise, accomplishing the initial vertical com pressionof the bale. Since the ram of the middle or larger cylinder 24 for themovable platen moves forward at the same time with the movement of theend rams 2d, the suction thereby induced in the middle cylinders 24;causes the water to flow from the tank 88 through the pipe 97, past thecheck valve 99, and through the pipe 95 and to follow closely behind theram of the middle cylinder. As the pressure still increases, and when itreaches a predetermined point, the check valve 96 opens, whereuponactive pressure is directed from the pipe 90 through pressure valve 96and into the pipe 95 and thence into the lower end of the middlecylinder 24, so that all three of these cylinders 2 1 are now underpressure, and the final vertical compression of the bale is accomplishedmore slowly than was the initial vertical compression accomplished bythe two end cylinders 21, but with greater power, corresponding to theincreased re sistance oftered by the bale.

When the compression has been completed and it is desired to release thebale, it is first necessary to manipulate the three-way valves 105 and112. The valve 105 is turned so that the water on the underside of thepiston in the cylinders 31 may find a way through the pipes 107 and 106through the valve 105 and the pipe 108 into the tank 88. The valve 112is turned so that the fluid pressure induced by the pump 89 may find away throughthe pipe 90 by way of the pipe 102 through the pipe 110 andthrough the pipes 114 and 116, into the upper ends or the cylinders 31above the pistons thereof. In the meantime, the pressure is held in allthree of the cylinders 2st. The effect of the pressure passing into theupper ends 01. the cylinders 31 as described is to lower the pistonsthereof, whereby the release of the compression of the end doors andside door is brought about. This release is withoutshock, because as thefluid pressure enters the upper ends of the cylinders 31 the pistonsthereof are driven downwardly and force out the fluid from theundersides oi? the pistons,'which fluid acts as a cushion. The. side andend doors being thus released, and the bale tied; the fluid pressure isdis continued by stopping the pump, whereupon the globe valve 101 isturned so that the threecylinders 241 may be vented into the tank 88,the middle cylinder by way' ofthe pipe 100 and the two end cylinders-2 1by way of the pipe 90, through the valve 91, which for this purpose is acheck valve as well as a pressure valve, through the pipe 102, throughthe union 109, pipe 110, valve 112, and by way of the pipe 115 to thetank 88.
